The Pre‑Marked Iris Ring 1–32 works with Teradek’s RT Lens Mapping feature. This allows you to assign a lens to a pre‑marked ring, save the settings, and recall them from the controller at any time.
After changing lenses, you can use the saved configuration instead of repeatedly calibrating the iris markings manually.
This is an iris ring, not a focus ring. The white scale is marked in the range of 1–32, and the product is labeled “RT Iris.”
Always verify the mechanical fit based on the lens being used and the lens control system configuration.
